FOLSOM, Calif. — Intel Corp. announced its first solid-state drives using its 3D XPoint memory chips. The Optane SSDs are expected to establish a small, but significant, beachhead for the technology, which is one of several alternatives pioneering a new market between flash and DRAM chips.
LAKE WALES, Fla—The inventor of 3D monolithic chip technologyback in 2010, BeSang Inc. (Beaverton, Ore.), claims to have since created a superior three-dimensional (3D) architecture for NAND flash. Frustrated withlicensee Hynix'sslow implementation of its monolithic 3D technology, BeSang is opening the door to partnerships with other memory houses, as well as offering to contract-fab the chips for resale by others, at a price that reduces the cost-per-bit of 3D NAND from over 20¢ to about 2¢ per gigabyte.
Problems with conventional 3D NAND are discussed including cell size, vertical scaling limitation, inefficiency of product architecture, and how BeSang aims to remedy them.
